Title: Improvements in and relating to the Compression of Elastic Fluids.
Inventor: FERRANTI SEBASTIAN ZIANI DE
Filed: 1902-10-20
Granted: 1904-01-20
Abstract: 22,846. Ferranti, S. Z. de. Oct. 20. Compressing air &c. by means of water, oil, mercury, or other liquids ; a centrifugal thrower or pump is employed to give the liquid the necessary velocity to compress the air through tubes into a receiver, the liquid being divided into separate plugs or pistons which carry the air between them along the tubes. In the arrangement shown in Fig. 1, the tubes a radiate from a chamber in which the thrower b rotates ; they increase in diameter towards their outer ends, in order to reduce the velocity of, the liquid, and are bent inwards for connection to annular receivers f, which communicate by pipes h with a separator i. The water is led back by the pipe l and through the cooler m to the nozzle c, which may be contracted, in order to increase the velocity and prevent leakage between it and the opening in the thrower. The air, or some of it, may be drawn in round this nozzle. In this apparatus, the liquid is divided up by the movement of the thrower itself past the mouths of the tubes a. Fig. 8 shows an arrangement in which a stream of liquid from the pipe 14 is delivered to a ring of tubes by means of a rotating nozzle 9. In a modification, a swinging nozzle is used. The liquid may be worked in an open or closed cycle including a turbine or other motor upon which the energy of the spent liquid is utilized. Fig. 6 shows an arrangement wherein the liquid. issuing from the tubes a, which pass through a water jacket, impinges upon an impactwheel 4 on the spindle of the thrower b which also carries an electric motor x. The tubes are made long enough to contain more than one liquid piston at the same time. The air may be humidified during compression by means of spray.

Patent GB-190228646-A (GB)
Title: Improvements in the Manufacture of Fabrics Coloured with Indigo.
Inventor: RIBBERT JULIUS
Filed: 1902-12-27
Granted: 1903-12-03
Abstract: 28,646. Ribbert, J. Dec. 27. Dyeing.-In the manufacture of fabrics dyed with indigo, paste resists which are commonly employed in the process for " printing blue," in which the fabric is impregnated with reduced indigo after the application by printing of the paste resist, are employed in the " indigo printing " process " in which unreduced indigo is printed on and is reduced on the fabric by previously-applied reducing-agents, such as glucose. By this means the back of the fabric may be dyed in lighter shades than the face. In the process, the fabric is impregnated with glucose, dextrose, or other indigo-reducing solution, and dried, a paste resist of ordinary composition being then printed on the face. After the resist has dried, the fabric is printed, padded, or partly covered on the face with an alkaline indigo print colour, and is then dried and steamed to reduce the indigo. Washing with water or acid developes the colour and completes this part of the process. As, however, the paste retains its resist property, the fabric may be further treated, after the steaming, in a plunging- vat or, preferably, in a continuous vat to colour the back. The fabric is finally treated with acid and washed. The back may be dyed in any desired shade, or, if the resist has been applied to it, printed in patterns. Ordinary modifications in the process may be produced by the use of acid resists or mixtures of paste and sulphur resists. A suitable resist for use in the above process is made up of verdigris, copper sulphate, pipe clay, lead sulphate, burnt starch, lead nitrate, sugar of lead, mucilage solution, copper nitrate, and alum. Another resist to be used in the production of white contains verdigris, copper sulphate, zinc sulphate, copper acetate, acetic acid, china clay, burnt starch, mucilage solution, and copper nitrate. The alkaline indigo print colour used in the process consists of a mixture of corn starch, British gum, caustic-soda solution, and an indigo mixture containing indigo, paste, and caustic soda.

Patent GB-190307590-A (GB)
Title: Improvements in Electro-magnetic Mechanism for Producing Reciprocatory Motion.
Inventor: MOULD JOHN THOMAS
Filed: 1903-04-01
Granted: 1904-02-04
Abstract: 7590. Mould, J. T. April 1. Motors, electromagnetic.-Relates to electromagnetic mechanism for producing reciprocatory movement, in which the circuit of the actuating- electromagnet is made and broken by a switch controlled by the reciprocating part without the intervention of rotary mechanism. The invention is applicable for use with the starting and regulating switches of electric motors &c. In the arrangement shown in Fig. 2, a plunger b is reciprocated by electromagnets a, t, each connected by wires w, o to the negative lead, and by wires u, v to contacts 5, 9 respectively. A bridge c, carried by the plunger, at one end of its course connects contacts 1, 2 and closes a circuit through the wires m, e, bridge c, wires f, g, coil of an electromagnet h, and wire j. The armature k of the electromagnet h is then moved, causing the bridges l and p to connect together contacts 5, 3, and 6, thus energizing the electromagnet a and drawing up the plunger b. As, however, the bridge c connects contacts 7, 8 connected respectively to the contacts 6, 2, the electromagnet h remains energized until the plunger reaches the end of its movement and disconnects the contacts 7, 8. The armature k then causes a bridge u to connect the contacts 9, 10 and energize the electromagnet t, which then moves the plunger back again. As the contacts 3, 6 are now disconnected, the circuits are not altered until the bridge c again reaches the contacts 1, 2. In a modification, the wires v, w, electromagnet t, contacts 9, 10, and bridge u are dispensed with, the plunger returning by its own weight or through a spring. The speed of the plunger may be regulated by a dash-pot or other retarding-device.
